Overview
The Glacier Fresh GF-34 is a two-pack of NSF-certified activated carbon replacement filter cartridges, sized at roughly 9.7 by 2.3 inches. It suits households replacing an existing cartridge-style filter of the same dimensions rather than buyers needing a full filtration system.
Glacier Fresh sells this as a like-for-like cartridge swap, not a standalone unit, so it only works if your current housing or fridge already takes a filter of this size. The listing does not name specific compatible appliance models, so measure or match your old cartridge before ordering. NSF certification covers material and structural claims, but specific contaminant reduction figures are not detailed here.
- NSF-certified activated carbon filter
- Pack of 2 cartridges
- Dimensions 9.73 x 2.33 x 2.33 inches
- Brand Glacier Fresh, model GF-34
Who it's for
Buyers who already own a filter housing or refrigerator that uses a roughly 9.7 by 2.3 inch cartridge and just need a certified replacement. Not a fit for anyone shopping for a complete filtration setup, since this is the cartridge alone.
Strengths and trade-offs
Drawn from this product's published specifications.
- NSF certified media
- Two filters included for less frequent reordering
- Compact cartridge fits many standard housings
- No listed compatible appliance models
- No description or reviews provided for buyer feedback
Performance notes
As an activated carbon cartridge, it filters by adsorption as water passes through the carbon media, the standard mechanism for reducing chlorine taste and odor along with some particulates. Filter life depends on household water use and is not specified in this listing, so replacement timing should follow the housing manufacturer's guidance.
